I want to copy a file from a pc to a server using impersonate (<username,password>).
When I wrote the follwing code and run it exception was thrown "logon failure unknown username or bad password".
Can anyone help?

C#
using (new Tools.Impersonator(Serv_UName, "",Serv_Pwd))
{
    if (File.Exists(DestFileName))
    {
        MessageBox.Show("already exists in destination");
        return 1;
    }
    else
    {
        File.Copy(Src_FileName, DestFileName, true);
        return 0;
    }
}

Try copy and pasting into a new class in your app. Add your applications namespace.
And then try it to see if it works.

Is the computer you are trying to talk to on a domain? because you dont appear to be sending a domain?

no domain
The error message you are seeing is pretty clear - you haven't provided credentials that it can correctly authenticate with.

You say you are connecting to a server - so what account are you expecting to use to authenticate against the server? A domain account, or a local account on the server?

The arguments you are providing are

Serv_UName, "",Serv_Pwd


What is the middle argument? Is it 'domain'? If so, try the following

Serv_UName, Serv_Name, Serv_Pwd


So if I wanted to connect to a server called SERVER1 with account dmorley, it would read

using (new Tools.Impersonator("dmorley", "SERVER1", "S0mePa55word"))


You need to make sure that the account exists on the server you are connecting to

So, a local account on the server?

In what context is the account you are using? Where is the account defined?
Reem Moh 2-Jun-11 4:48am    
wt u mean!!

Where is the account defined - It must exist somewhere! Where has the account been created?

If you don't understand this, it's not suprising that you're seeing a 'logon failure' message
